Monobeasts

The monobeast is a vermin which detaches from a Patient suffering from Monobrow. It then moves independently throughout your hospital. When you mouse over a monobeast, the cursor becomes a targeting reticle. You may then exterminate the monobeast, so that a Janitor may dispose of its remains.

In Lower Bullocks you can asked to kill 10 Monobeast to get an revard.
